Application filed August 9,1909. Serial No. 511,880.

T 0 all whom it may concern Be it known that I, PIERRE VIRY, citizen of the French Republic, residing at -Suresnes,lDepa1-tment of the Seine,in .France, have invented certain new and useful Im .provements in Electrical Devices for Gontrolling 'from .a Distance Any Number of Movements; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

The present invention has for its object an electric device for controlling from a distance any number of movements by means of two wires, or when an earth'return is. used by a single Wire. This arrangement is represented by way of example in the accompanying drawings, in which Figure 1 is a general diagrammatic view. Fig.2 is a diagrammatic view of the receiving station. Fig.3 is a diagrammatic view of a modification of the system. Figs. 4 and ,5 represent. a modified detail. .Fig. 6 shows a special arrangement of the .receiving station. Fig. '7 illustrates a construction of the controlling keys.' Fig. 8 represents a difi'erent method of arra ing the two stations. 'Fig. 9 represents a eitail of mitting station A (Fig. l) and a-receiving,

station B united by twowires C, it being understood that one wire only'is necessary 5 when an earth return is used. a

The vibration periods of these plates 'di'ifer very sl' htly in passing 'from their .vibmtions may small coils b b c'c 0. One or other of the,plates i s rendered o erative'bypressingnpon one of .the knobs 'd .d which closes the circuitof the correspondingplate and imparts the first impulse to thisplate. Pressure upon'a dmob therefore causes throughout the dura- -.tion of this pressure the emission in the'line of a vibrated current, the period of which is equal .to that of the corresponding plate. Admob eenables a continuous current to be sent through the line. 'The knob-e may be *an ordinary circuit closer having its contacts a; the number n is equal to that of the movements'to be obl k normally-separatedhya spring orlthe The receiving station comprises vibrating plates 7" f f tuned aVVlt-h'thGlPlfitES of the transmitter respectively. In front of eachplatethere is a coil 4 all:the coils jg g g" are arranged in series. Associated with each plate 1 is a beam h (Fig. 2), provided with a ,pziwli capable of engaging with the head of an iron-clad electro-magnet around which all the plates are arranged. The beams k may be drawn back by the springs 70. Carbons'l carried on the extremty. of the. beam permit of establishing the necessary connections with the fixed carbons in. and M for the control to be effected. Normally, all the pawls are locked and a switch 0 sends the line current through the mitting station be pressed, the emission of vibrated current resulting therefrom roduces the irib'ration of the plate f at the receiving station and of this plate f only; the plate acts upon the pawl i the beam h is released and the carbons Z and m or M" establish the connections corresponding to the control of the knob d. is released its extremity opposite to the ,carbons strikes against the switch 0, the current is thereby interrupted in the small coils and sent into the ironclad coil q; the plate f ceases to vibrate; the plate a of the transmitter continues to vibrate so long as the operator presses on-the button, but he need not continue to press as soon as the control has been produced. In order to cause the movement produced by this control to cease it is only necessary to bring the beam back into its normal position. VVith this object the operator at the transmitting-stationpresses upon the knob n: he

thereby sends a continuous current through the iron clad coil; its core is attracted and the switch 0 carried by the upper rod of the core depresses the beam and produces the reengag'ement of the pawl 2'". When the operatorreleases the knob e. a spring returns the core of the coil to its normal position. and the switch again places the line in communication withlhe small coils in series; the apparatus is ready for a fresh control.

The device which has just been described is applicable to the control from a distance of all electric motors or electromagnets uti- When the beam.

Nevertheless, exam ples may be cited of: the application'of the invention to controlling aprojector from a distance' In this; case the apparatus may comprise eight controls (1) One for the movement of rbtat-ion of the projector to right quickly-7? ":.(2)' One for the move ment of rotation of the projector to right slowly (3) One for the movement of rotation of the projector to.left quickly. (4:) One for the movement of rotation of the projector to left slowly One for the vertical movement of the projector I higher. (6) One for the vertical move- 7 One ment of the projector lower.

Aspring 3 maintains the lever a ainst the pawl, and aspring ii presses he pawl 2 against the beam h.

Fig. 6 represents diagrammatically a method of mounting the receiving station which enables theswitch oto be dispensed with. One of the extremities of the winding of the coil 9 is eonn'ected with one of the line wires, The arrangement is such thatwthe time constant (ratio of the selfinduction to the ohmic resistance) 'of the central coil 9 is very igh relativelyto the constants of the coils -9. In this manner the vibrated currents pass almost entirely through thesmall coils while the continuous currents pass through the central coil.

In the installation" illustrated in Fig. 1, it is necessary, in order to stop the move:

. ment, to press upon'a button'e which causes the emission of continuous currenti- Fig. 7 represents a' device in which nov stop press buttons are necessary; the move at 12 for retarding the movement.

cease-by releasing this button. In the iii-'- operative position each button d is main- 0 tamed at rest by a spring 15 as shown-.111]? Fig. 7. Upon its rod there is fixed a tappe t at the upper part of the vibrating plate a. A contact 14- fixed to this-plate is arranged 9 which is arranged to abut a plate formedto contact with a button 0. The tappet' v carries at its lower partan insulating piece 10 beneath a flexible strip 11 which tends tocome into contact with a key 16" elec trically connected with the extremityof thecoil 5. When the button (Z is pressedlthe:

tappet 9 releases the plate a which is then able to vibrate and establishes intermittent contacts at c. This strip 11 rests upon the key 16 and closes the circuit. It conse quently'sets up a vibratory current as indicated above. When the button d is released the tappet in abutting the top of the plate ar presses the contact 14 upon the contact a which causes a continuous current to pass and returns the beam 72. at the receiving station to its normal position.- When the button reaches the end of its travel the insulating part 10 lifts the strip 11 and interrupts the current. In order that the passage of the continuous: current may gcontinue for a sufiicient length of time to return the core of the central coil 9, a dash-pet is arranged The transmitting. station A is in this case constituted by a transformer a: comprising as many primary circuits as there are vibrating plates a, that is. to'say, as there are distinct movements to be controlled'. The vibrating plates (1. a a 'e'tc.,

transformer have their vibrations maintained electrically by'means of the vibrating" contacts 0 .0", etc. lhe different primary circuits are mounted in parallel and connected with the terminals by a source'of. v electricity G arranged at thetransmitting I1 '6' station. The secondary wlndlng f'of f-the arranged in proximity to the core of-the transformeris connected i'with the two-line dered operatia e by acting upon the-interrupters 1'' 1*, etc. The} receiving-'stationB comprises n coils, 2;";9 mounted in'series and connected withthetwoiline wires '0.

Each of the vibrating plates such as f may thaothei flexiblearm' to may close a local wires C. The various plates "can be "ren act upon a flexible army'- (Fig. '9) carrying a contact/ 13. This contact pressing upon circuit. comprising a coil 1). The core of these coils makes the contacts m or M according to its position. The successive shocks in the vibrating plates upon the flexible arm 0 produces a continuous pressure of the contact 13 upon the contact w during the whole time that the vibrations last. This result is obtained by appropriately selecting the oscillation periods of the vibrating plate. Two flat springs .2 produce a braklng action upon the movement of the flexible arm y. In these conditions the movement corresponding to each interrupter 1- of. the transmitter is produced during the entire period that the interrupter is closed. Several movements may therefore be controlled simultaneously and independently of each other owing to the principle of the superposition without confusion of small electric oscillations in one and the same circuit.
